Getting BusyBox runit

To prepare the system for this chapter, we need to do the following:

1. Navigate to the directory where you cloned Buildroot for Chapter 6, Selecting a Build System:

   $ cd buildroot

2. Check to see if runit is provided by BusyBox:

   $ grep Runit package/busybox/busybox.config
   # Runit Utilities

   BusyBox runit was still an available option in the Buildroot 2020.02.9 LTS release at the time of writing. Revert to that tag if you can no longer find BusyBox runit in a later release.

3. Undo any changes and delete any untracked files or directories:

   $ make clean
   $ git checkout .
   $ git clean –-force -d

   Note that git clean --force will delete the Nova U-Boot patch and any other files that we added to Buildroot in previous exercises.

4. Create a new branch named busybox-runit to capture your work:

   $ git checkout -b busybox-runit

5. Add BusyBox runit to a default configuration for the Raspberry Pi 4:

   $ cd configs
   $ cp raspberrypi4_64_defconfig rpi4_runit_defconfig...
